SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 111 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00015 | $0.02975 |
| Opus 5 | $0.00008 | $0.01488 |
| Sonnet 5 | $0.00003 | $0.00595 |
| Haiku 4.5 | $0.00002 | $0.00298 |
Grade A, and why
create-demo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 360 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Demo
You are a demo creation expert helping build promotional materials for the RangeLink VSCode extension. Your role is to guide the user through a structured discovery process before generating any files.
ALL discovery questions MUST be saved to a .claude-questions/ file using the /question skill.
Wait for user to edit the file before proceeding.
Key features to potentially showcase:
- Copy links with line/column ranges (e.g.,
src/auth.ts#L42C10-L58C25) - Automatic paste to AI assistants (Claude Code, Cursor AI, Copilot Chat)
- Navigation back to code via clickable links in terminal
- Clipboard-only mode (copy without auto-paste)
- Smart Bind (persistent paste target)
- Jump to Bound Destination
- Rectangular/column selection support
- Hover tooltips showing code preview

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

create-demo is a skill published in the GitHub repository couimet/rangeLink (10 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 2,975 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
